Was the formation of Earth unique or was it similar to the processes which created all the planets in the solar system?

The formation of the Earth was almost identical to the formation of the other three terrestrial planets (Mercury, Venus, and Mars) until a very unique event happened.
An unusually large object estimated to be roughly the size Mars is now struck Earth just after Earth had first formed a solid crust, at just exactly the right place and angle to gouge out a large piece of Earth's mantle, completely remelt both Earth and the object, and fling most of the ejected mantle material into an orbit around Earth where when it cooled the ejected mantle material became Earth's Moon. Had this impact been even slightly different it could have either totally shattered Earth creating another Asteroid Belt or the large object could have simply glanced off leaving Earth nearly as it was.
The formation of the four terrestrial planets and the four gas giant planets was very different, influenced largely by the variation in intensity of sunlight in the early solar system.

Which planets gas might be close to the amount on earth?
If by gas you mean an atmosphere, there are no planets with an atmosphere anywhere similar to Earth.
How does mixing concrete and allowing it to harden is similar to formation of sedimentary rock?
Both processes include sediments and water, with the water facilitating the setting of the material. However, sedimentary rock tends to form under pressure, whereas the hardening of concrete just requires it to dry out.
Describe two ways earth is like the other planets in our solar system?
it is a planet and it has a similar shape like the rest of the planets.
Which planet has 300 times greater mass than earth?
In our Solar System, Jupiter has approximately that mass. Many of the extrasolar planets discovered so far have similar masses as well.
If Rene Descartes created a similar system of scientific notation what was the original system?
Descartes and His Coordinate System.
How are inner planets similar to dwarf planets?
The other planets are not similar to dwarf planets.
How are the inner planets similar to dwarf planets?
The other planets are not similar to dwarf planets.
How are gas giant planets and terrestrial planets similar?
They are are not similar.
How is Mars and earth alike?
Mars and Earth are very different planets when it comes to temperature, size, and atmosphere, but geologic processes on the two planets are surprisingly similar. On Mars, we see volcanoes, canyons, and impact basins much like the ones we see on Earth.
How are outer planets similar to inner planets?
They are similar in that both the inner and outer planets all orbit the sun.
Are comets more similar to the inner planets or the outer planets?
They are more similar to the inner planets, since they are rocky and icy in nature instead of gaseous.
How are oogenesis and spermatogenesis similar?
Oogenesis is the formation of the ovum, and spermatogenesis is the formation of the sperm. These two processes are similar as they are both formed by meiosis, (reduction division). Meiosis is the process of cell division where one mother cell will create four daughter cells with half the amount of genetic information. Or in other words, oogenesis and spermatogenesis are creating gametes.
How are the processes of digestion and absorption similar?
The processes of digestion and absorption are similar because they both involve absorbing a substance. :)
Are the jovian planets similar in mass to the terrestrial planets?
No. The Jovian planets are much more massive than the terrestrial planets.
How are the inner planets similar to the sun?
They are not very similar at all.
Rock similar to that which formed planets?
the similar rock is asteroid.
What are the outer planets and how are they similar?
The outer planets are the planets that are made of gas. Each of the outer planets are mad of gas and can not hold life.
